Convert WEBP files directly into ICO in your browser. 100% private WebAssembly processing, no uploads required.
Output format
WebP files are converted to ICO entirely on your device. Your images are never uploaded to a server.
Add many WebP files at once and convert them all in a single click. Each file has its own progress indicator and status, and you can download everything as a ZIP at the end.
No estimated savings — the actual output bytes are shown, so the percentage saved you see is what you actually get.
For lossy ICO output a 1–100 quality slider trades size against visual quality. The tradeoff is explained inline.
